Statement of the problem. In practice, the problem of determining the coordinates of a laser radiation source often arises under conditions when the reception and analysis of direct radiation is difficult due to the high power and spatial extent of the monitoring object.

Purpose. Evaluation of the possibility of determining the coordinates of the monitoring source of laser radiation from the radiation component scattered on particles of atmospheric aerosol.

Results. Based on the use of a mathematical model of the formation and transfer of scattered continuous laser radiation, estimates of the coordinates of photosensitive elements of rows with the maximum values of image intensities and an algorithm for estimating the position of the laser beam of a matrix photodetector against a background of Gaussian noise using complete sufficient statistics of the received scattered radiation, an algorithm for estimating the coordinates of the monitoring source of laser radiation in space.

Practical significance. The proposed algorithm for estimating the coordinates of a monitoring laser source in space, provided that there is a priori data on the range near located objects, makes it possible to determine the coordinate of the monitoring laser source from the component scattered in the atmosphere.
